AUTOMOBILE DRIVING .A'.l.\l'll.l- S UPPQRTING WHEEL.

1'0 all whom it may concern:

lle it known that I, PRESTON H.. Basso, a citizen of the United States, residing at Pittsfield, in the county of Berkshire and State of Massachusetts. have invented certain new anduscful Improvements in Automobile Driving and Supporting Wheels, of

which the following is a specification, referenec being had therein to the accompanying drawing.

' automobile driving and supporting wheels,-

and pertains more particularly to that t y e to which driving sprockets are operative y attached.

The primary object of the present invention is to so arrange and construct the wheel and its coilpcratiug parts that the wheel can be detached from the. driving hub without disturbing-the driving meehan'ism. mthe driving liub bearings. ,7 a

In the accompanying drawings, Figure 1 is a vertical sectional view-taken through the center of the wheel. Fig. 2 is an en larged central sectional view, omitting the driving-mechanism, and showing only part of the chain case. Fig. 3 shows a modification in the construction .of the hub-cap.

The presentin'iprovements are shown as applied to a sprocket'and chain driven suporting and driving wheel, though some of its features are. capable of use with other forms of driving mechanism. In this type,

1 is a stationary supportin axle whieh is attached to the vehicle any desired main or driving hub 2, and an auxiliary, or

wheel hub 3 are provided. 'When the. improvement is used with the stationary axle and sprocket and chain type here-shown, the main or driving hub 2 1s journaled on the axle, as for instance, the roller or other bear ings 4, which are so well understood by those skilled in the art'that further description is unnecessary. This arrangement. however willbe modified when applied to other forms of driving mechanism as may be required.

The spokes 5 of the wheel radiate from the auxiliary or wheel hub 3. The inner end of this hub is provided with a lateral annular flange 6. and the inner ends of the -spokes 5 are clamped between the flange 6 Specification of Letters fatent.

annular flange 9 projects from the driving hub 2 intermediate its ends, and when the wheel" withits auxiliary hub 3 is placed on the driving, hub. the flanges '6 and 90f the two hubs fit against each other as shown, and are clamped together by a suitable number of bolts 10. These bolts clam the two hubs together, and cause the auxi iary hub and the wheel to rotate with the driving hub. The heads 11 of the bolts 8 for the-auxiliary hub are counter-sunk in the flange 6, as shown, top rmit the flanges 9 andG-to fit. against eac other as illustrated.

A cap 12 is provided for thedrivinghub 'and as shown in Figs. 1 and 2, the outer en of the driving hub hasinternal screw threads 13, and the cap external screw threads 14.- meshing therewith. The cap closes the open outer end of the driving hub, andis provided with an annular flange 15 rejecting across the outer end of the auxiliary hub 3, andcan be used to assist in ,forcingthe saidv hub to position on the driving 'hubfand also to "assist in-holdingQ or Locating the auxiliary hub on the driving From the foregoing it will be seen that the wheel 'and its auxiliary hub, which constitute a complete wheel, can be readily removed from the driving hub without distturlziing the latter, and as will be explained hereinafter, without disturbing in any manner the driving mechanism;

As shown the inner end 16 of the driving hub projects inward beyond the flange 9, an

to this end of the hub, the driving sprocket teeth 17 are attached. This sprocket may be made of various forms-without affecting the primar invention here disclosed, but in the form cross-section, with the sprocket teeth 17 on the outside of its rim 18, with .its part 19 attached to an annular flange 20 of the hub by 'bolts'21. .,By this arrangement, the

inner side of the rim 18 utilized is-=1 braking drum 02:.s'urface, and the parts of the expanding'bralte (not shown) will supported bythe parts 22, 23 and-24:.

A driving chain (not shown) of course cooperates with or engages the sprocket teeth 17, and a chaincase is supported by the stationaryaxle 1. In carrying out this part of the construction, a sleeve 25 is rigidly attached to the axle 1, and'the inner wall 26 of the chain case 27 is bolted to this sleeveby ere shown it is cup-shaped in I ner side of the inner end of the driving hub,

the bolts .28. The outer wall 29 is preferl ably detachabiy connected with the case 27, by bolts 30, and the inner edge of this wall has an annular opening, thewall 31 of which is provided with a suitable dustexcluding and oil retaining padding 32. A suitable packing 33 is also arranged between the inand the axle.

From the foregoing description and illustration, it will be understood, that the wheel with its auxiliary hub can be easily detached without disturbing the chain, its adjustment, the sprocket wheel, the chain case, or the wheel bearings, and also enables a dust roof and oil retaining construction to be ma e.

1 have here disclosed the preferred form of the invention. but variations may be made the broad invention.

The wheel is here shown as having spokes, but it is to be understood that variations as tot-his usual construction may be made without departing from the invention, and the use of the term spokes in the claims is to be construed to include other forms which perform the function of the spokes men-,

tioned in the claims.

l lai'ing thus described my invention, .wluu I claim and desire to secure by Letters Patent is:

1. The-combination with a stationary axle, of a wheel comprisingnn auxiliary uh, a main hub detachably telescoping the auxiliary hub, a driving member attached to the innerend of the main hub, and a casing secured to the axle embracing the dri 'ing member and havin the inner edge of its outer Wall surrounding the inner end of the hub for the purpose described.

2. The combination-with a stationary axle, of a wheel com rising an auxiliaryhub, a main hub detac iably telescoping the auxile iary hub, the inner end of the main hub car rying a driving member, a casing embracing the drivin member, the inner wall of the casing firm y attached to the axle, and a detachable outer wall having its inner edge fitting closely the inner portion of the hub.

In testimony whereof I affix my signature in presence of two witnesses.
